Science: Deepest

Having broken a winch while sounding the Caribbean and adjacent
Atlantic, Eldridge Reeves Johnson's yacht Caroline put into San Juan,
P. R. last week. Immediately Dr. Paul Bartsch, Smithsonian
naturalist, sped ashore to report the discovery of the greatest known
crack in earth, a deep of 44,000 ft. (8.33 mi.) just north of Puerto
Rico. Also off Puerto Rico is the Nares Deep (27,972 ft., or 5.30 mi.),
greatest previously known hole in the Atlantic.* Both deeps lie in a
lively seismic zone, indicate how the earth's crust warps and cracks.
